Question

Calculate the frequency of a second’s pendulum.

Answer 1

Answer:

time period of second pendulum=2 s

frequency = 1/T

                 =1/2= 0.5 $s^{-1}$

Answer 2

Answer:

Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s . Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz . You can also let this simple pendulum calculator perform all calculations for you!
